SPEGIFIGATION forming part Qf Lttet's Patent N0. 691,668, dat-ed. January 21, 1902.

Application filed November 6, 1899. Serial No. l735,920. (No model.) l I i To a/ZZ whom t may concern: k

Be it known that LCHARLES RUPP,of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Skylights, whereof the following is a specication, reference being had to the accompanying drawings.

My improvements are peculiarly applicable to skylights comprising large spans-such asA form the roofs of train-sheds, mills, and similar structures-which are subjected to vibration from the action `of the wind, the movement of trains, travelingcranes, heavy machinery, dac. work of sash-bars, upon and between which aregmounted sheets of glass forming panels. In order to form a water-tight joint between the edges of the glass and the supporting-V framework aforesaid, it is usual to rigidly secure the glass upon anges of said sash-bars beneath a ductile metal'glazing-strip compressed thereon to iit the inequalities of the glass or to embed the edges of the glass in cement lodged on the flanges of said bars in `rigid relation therewith. Any form of skylight wherein the glass is rigidly secured to the sash-bars is objectionable, in that the eXpansion and contraction of the glass and framing, as well as the vibration thereof due to moving loads adjacent thereto, sufce to either shatter the glass orloosen the same and destroyits water-tight connection with the sash-bar.

Therefore it is the object of my invention to provide means whereby the sheets or panels of glass may be mounted on the sash-bars to vibrate loosely with respect thereto without permitting the iniiux of rain-water, dac.; and to secure such result I provide each of said loose panels with marginal strips fixed thereonindependent of said supporting structure and projecting above the surface of the glass, as hereinafter more particularly described.

In theaccompanying drawings, Figure lis a Vertical sectional view showing a portion of a skylight embodying my invention. Fig. 2 is a perspective view showing a fragment of a panel of glass with my improved pocketed strip secured upon the margin thereof. Fig. 3 is a cross-sectional view of a wrought-metal sashbar,showin g an embodiment of my invention. Fig. 4 is a cross-sectional view of a sheet-metal sash-bar,showing an embodiment Such spans comprise a frame-y vof my invention. Fig. 5 is a cross-sectional view of a combined wrought-metal and sheetmetal sash-bar, showing an embodiment of my invention. y

Referring to Fig. l, IA A are nrembers -ofv the framework, upon which are mounted sash bars B, said bars being connected transversely by means of the head-bar C and curbing D. The glass plates E extend from barv to bar and are upheld by the flanges b c d. yEach,

of the panels of glass is independently framed with marginal strips F, which are pocketed, as shown in Fig. 2, to receive a filling ofvany suitable cement G, within which the edges of the. glass are embedded"` and by" which each Vstrip F is secured in permanently rigid rela-v tion with the glass. It is therefore to be understood that each sheet of glass, however fluted or otherwise` unequal itsr surface may` be, is provided with a planular margin of said strips F, and thus adapted to rest uponand loosely vibrate with respect to the supportingframework of sash-bars, dac., from which it is, however, wholly separate.

As shown in the several figures, the strips F form ledges f, project-ing above the upper surface of the glass E a sufficient height to prevent the rain-water, which traverses said surface, from overflowing upon the flanges b of the sash-bars B, by which the glass E is upheld, as shown in Figs. 3 to 5, inclusive. The caps H, which cover thevertical webs b of the sash-bars, overlap the strips F and prevent the fall of rain or snow at the junctions of the glass and sash-bars. Said caps H do not, however, bind the glass plates E or in any manner interfere with the freedom of movement thereof.

Although the ledges f suffice under normal conditions to prevent any lateral overflow from the glass plates E, I prefer to provide the strips F with drip-flanges F', depending below the lower surface of said plates, to prevent the possible discharge of water upon said lower surface, and said flanges F overhang the gutters B of the sash-bars to insure the discharge of any drip therein.

When the panels between the sash-bars B are of such length as not to be conveniently formed with single plates of glass E, I prefer to resort to the butt-joint shown in Fig. l. Said joint comprises a cross-clip Lwhich serves IOD to support the adjoining edges of the respective plates E in alinement, as shown, and is conveniently provided with a gutter I and vertical web i. In this form of my invention I prefer to cement the cap-plate J between the upper surface of the glass plate and the adjacent flange of the pocketed strip F, said cap-plate serving to shed the water from the upper to the lower portion of the panel, as may be understood by reference to Fig. 1.

1t is to be understood that my invention is not limited to embodiment in sash-bars of the particular forms which I have shown, but is applicable to any convenient form of sashbar provided with a cap arranged to shed the water away from the loose joint made by the pocketed stri ps F, resting upon the sash-bar.

I believe it to be new to provide a skylight-plate with marginal strips xed in rigid relation therewith and to mount said plate in a supporting-framework in such relation therewith as to permit of its free vibration with respect thereto. I therefore do not desire to limit myself to the precise construction or arrangement of the parts which I have shown and described, as it is obvious that various modifications may be made therein withoutdeparting from the spiritot' myinventior'i. Y

I claiml. The combination With an independent glass plate of a skylight, of a Strip, fixed upon the margin of said plate, and projecting above the upper surface thereof, in watertight relation therewith, a drip-flange upon said strip, depending from the lowersurface of said plate, and a cap member J, secured beneath said strip and having a free edge projecting beyond the margin of said plate, substantially as set forth.

2. The combination witha skylight-frame,

of a glass plate mounted to vibrate loosely in said frame, a strip independent of said frame, xed upon the margin of said plate, in Watertight relation therewith, and a cap member secured beneath said strip, and having its free edge projecting beyond the margin of said plate, substantially as set forth.
